Description Anton Starikov 2011-12-27 03:12:20 UTC 
Description of problem:

I have solaris express 11 NFS server and linux clients. With older fedora-12 clients everything works as expected. But with fedora-16 it is broken (I have latest nfs-utils with fixed problem of reading domain from  idmap.conf )


Version-Release number of selected component (if applicable):
nfs-utils-1.2.5-3.fc16.x86_64

How reproducible:


Steps to Reproduce:
1. create proper /etc/idmap.conf
2. start rpc.idmapd
3. mount NFSv4 share
4. ls -l on mounted directory
  
Actual results:

# rpc.idmapd  -vvvvvvvvvvv -f 
rpc.idmapd: libnfsidmap: using domain: localdomain
rpc.idmapd: libnfsidmap: Realms list: 'LOCALDOMAIN' 
rpc.idmapd: libnfsidmap: processing 'Method' list
rpc.idmapd: libnfsidmap: loaded plugin /lib64/libnfsidmap/nsswitch.so for method nsswitch

rpc.idmapd: Expiration time is 600 seconds.

after mount, all UID/GID of files shown on local machine to be 4294967294 (which differs from local nobody, nfsnobody and from remote nfsnobody). The only exceptions are files owned by IDs which has no correspondent names on remote system. (For example if I chown to particular numeric ID which does not exist on remote machine, then on client it will be shown properly)

/var/lib/nfs/rpc_pipefs/nfs remains empty

Expected results:

when  start idmapd on older F12 system, it logs new client on mount and all attempts to resolve names to ids. on F16 log remains silent.

/var/lib/nfs/rpc_pipefs/nfs on F12 host if full of clntXXX directories.

I've got a feeling the bz is the same problem:

https://bugzilla.redhat.com/show_bug.cgi?id=800679

Could you also get a binary network trace using either 
   tcpdump -s0 -w /tmp/data.pcap host <server>
or 
   tshark -w /tmp/data.pcap <server>

The bzip2 the trace file:
   bzip2 /tmp/data.pcap
